There are two main components to a garage door: the door itself and the opener. In this article, we'll tell you how to make repairs to both things. We'll start with the actual door.

Repairing a Garage Door

Overhead garage doors, whether they roll up in sections or swing up in one piece, operate on spring tension. The door moves on metal tracks on the garage walls, and a heavy spring or springs provide the power. In most cases when the door doesn't work easily, repairs are fairly simple. Here are some helpful repair tips:Step 1: Check the metal tracks inside the garage. Look at the mounting brackets that hold the tracks to the walls. If they're loose, tighten the bolts or screws at the brackets. Working inside the garage with the garage door closed, examine the tracks for dents, crimps, or flat spots. If there are any damaged spots, pound them out with a rubber mallet, or with a hammer and a block of scrap wood. If the tracks are badly damaged, they should be replaced.
